imgSavePngIo function image

bool imgSavePngIo(
  1. Pointer<SdlSurface> surface,
  2. Pointer<SdlIoStream> dst,
  3. bool closeio
)

Save an SDL_Surface into PNG image data, via an SDL_IOStream.

If you just want to save to a filename, you can use IMG_SavePNG() instead.

If closeio is true, dst will be closed before returning, whether this function succeeds or not.

\param surface the SDL surface to save. \param dst the SDL_IOStream to save the image data to. \param closeio true to close/free the SDL_IOStream before returning, false to leave it open. \returns true on success or false on failure; call SDL_GetError() for more information.

\since This function is available since SDL_image 3.0.0.
